AudioQuest's patented Dielectric Bias System (DBS) puts all of a cable’s dielectric into a strong, stable electrostatic field which saturates (organises) the molecules of the insulation ... continuously from the time the cable is terminated. The exceptionally simple design uses a wire down the middle of the cable, which is simply an extension of a battery’s anode. This wire is attached to negative (-) of a DBS battery pack, and nothing else. It is not in the signal path and has no interaction with the signal.
